Hello,

Prob a tired topic but I will rebuild my 89, 3.2 engine this winter. It needs more HP. Assuming the jugs are in spec, what's the best Piston / CAM combo.

Single plug
Motronics ignition with SW chip.
cat delete with two out muffler
stock HE's
140k mi
Runs perfectly (some chain noise)
premium pump gas
will upgrade rod bolts

Are JE pistons better than Stock?

Thanks,

Chris
